UNITED STATES PATENT OFFICE.

WILLIAM BROWN, OF THOMPSON, NEXV YORK.

APPARATUS FOR HANDLING HIDES, &o., IN THE PROCESS OF TANNING LEATHER.

Specification of Letters Patent No. 1,079, dated February 9, 1839.

To all whom t may concern Be it known that I, lVILLIAM BROWN, of Thompson, in the county of Sullivan and State of New York, have invented a new and Improved Mode ot Tanning, called Browns Facilitating Apparatus for Tanning.

The nature of my invention consists in changing the position of hides, sides, and skins in the liquors in all the different processes of tanning, viz., liming, bating and tan ning, as a substitute for the ordinary mode of drawing', handling, and laying away.

To enable others skilled in the artI of tanning to make and use my invention, I proceed to describe its construction and operation, I construct my vats in any of the known forms as seen at A, in the accompanying drawing with the addition of the plank B across the vat A, and apply thereto an apparatus partially in the form of a rake, as exhibited by the heads D, handles E and stretcher C, a bow is attached to the head I), to which the handle E is aiixed by a leather strap that they may be at liberty to cross each other over the plank B. The object oit vthe stretcher O is to keep the heads D extended and its length is regulated by the length of the hides, sides or skins. The hides, &c., is attached to the heads D, by means ot' holes bored in the same about one inch apart through which a strap passes into co-rresponding holes made in the edge of the hides, &c. The number of hides, sides, or skins attached to each set ot apparatus may be varied from 10 to 25 to be governed by their Weight.

F exhibits end view of apparatus with hides, Sac., attached, g gives the side view of apparatus Wit-h hides, &c., attached, H a side of leather in progression.

The Whole being` immersed in the liquor as above described, the Workman Will take the handles E one in each hand moving along the plank B will thereby change the position of the hides, 6to., with ease and facility. Moving the sides from one side of the vat to the other changes their position by turning them upside down.

The operation will require about live minutes to remove 100 sides.

By the use of the above apparatus green stock may be kept extended and lie smoothly in the liquor Without` folds or doublings perniitting the liquor to come in contact with, and circulate freely among the leather, enabling the Workman to change its position With facility and frequently, which should be done once in ten minutes for the first hour and from tour to six times a day after- Ward which not only facilitates the tanning, but improves the quality of the leather.

That I claim as my invention and desire to secure by Letters Patent is- The construction of the above described apparatus and its application to vats of any and every description in all the different processes of tanning.

WM. BROWN.
